I made a big mistake in the previously-posted schematic of the connection between an Icom IC-2A, 2AT, or 02AT and a packet radio TNC, RTTY afsk unit, or another microphone. The resistor and capacitor were backwards. The correct schematic follows: Audio from TNC* PTT Ground | | | --- / | (C1) --- (R1) \ | | / | | | | Icom HT | | | mic input------+-------------+ | | ground--------------------------------+ C1 - 0.47 uf capacitor R1 - 25K resistor * TNC or RTTY afsk or another microphone or whatever you are interfacing to your Icom HT. -Tom KA2UGQ uucp: ..!ihnp4!bellcore!mtunh!ky2d-2!ka2ugq or: ..!ihnp4!bellcore!ka9q!tom packet: KA2UGQ @ WA2SNA-1 bomb: 40 41 N, 74 25 W 2m FM: 145.750 MHz (local simplex)
